Grand Slam of Darts 2021 Offer – MansionBet 2
Aim to lose no more than £1.00 on each of our 5 qualifying bets
So, we’ll lose approximately £5.00 in qualifying for each £10.00 free bet.
Our £10.00 free bets will be credited upon settlement of our five qualifying bets and will be valid on any sports market for 7 days. Free bet stakes are not included in any returns.
Using straightforward matched betting, we should be able to convert each free bet into 80% cash, so £8.00. If we take into account our total expected qualifying loss of £5.00, this gives us a daily guaranteed profit of £3.00!
With a maximum of 5 free bets to be claimed throughout the tournament, that’s an overall guaranteed profit of £15.00 on this MansionBet offer!
